Australia Application December 12, 1934, Serial No. 757,230

In Great Britain 10 Claims.

This invention relates tok a cooling device for liquids (for examplebeer or other beverages), and more particularly to a cooling coiladapted' to be subjected in a container to the action of a coolingmedium.

An object of the invention is to provide a cooling coil which may bemore easily dismantled and kcleaned than is the case with knownarrangements.

Apparatus for cooling beverages, according to the present invention,comprises, in combination, a plurality of tubes through which liquid caniiow, end-plates having conduits to communicate with the said tubes, anddetachable clamping means for retaining the said end-plates influidtight contact with the tubes. The tubes are preferably of glass andare separated from the endplates by gaskets (for example of rubber).

According to another feature of the invention, the gaskets are formedwith projections extending laterally beyond the said end-plates so as toform feet for supporting the apparatus.

Other features of the invention will appear hereinafter.

Specic embodiments of the present invention will now be described, byway of example, with reference to the accompanying drawing in which:-

Figure 1 is a plan, partly in section, of one form of the apparatusaccording to the invention,

Figures 2 and 3 are sectional elevations, taken along the line 2-2 andalong the line 3-3 respectively of Figure l.

As shown in the drawing, four glass tubes I0 are supported, at each endin rubber gaskets II formed with flanges I2 so as to make a spigotconnection with the tubes I0. End-plates I3 and I4, formed integrallywith an inlet conduit I 5 and an outlet conduit I5 respectively areclamped on to the gaskets II by nuts II engaging the ends ofscrew-threaded rods I8 which pass through slots I9 formed at each end-of the end-plates. Strengthening flanges 40 are formed integrally withthe end-plates I3 and I4. The nuts II are formed with diametral holes 20for engagement with a tommy-bar (not shown). Holes 2| and 22 are formedrespectively in the end-plates I3 and I4 to connect the inlet conduit I5and the outlet I6 with the tubes I0.

Projections 23 on the gaskets II extend laterally beyond the end-platesI3 and I4 so as to form feet for supporting the apparatus, and grooves24 (see Figure 3) in each end of the gaskets locate the tubes withrespect to the rods I8.

The apparatus, in use, is housed in a cold cham- December 11, 1933 tubesthrough the holes 22 into the outlet conduit 10.

I6 at the bottom of the end-plate I4. A joint 26 connects the outletconduit I6 to an outlet pipe (not shown).

It will be seen that the pipes I0 are connected in parallel with theconduits I3 and I4, and that if one of the pipeswere broken, theappropriate holes 2| and 22 might be plugged whereby the apparatus couldstill be used with only three tubes in operation.

Instead of glass tubes it is also possible to use 2O metal tubes forinstance of copper or bronze which are casttogether to form a singleunit.

It will also be seen that by slackening the tension nuts thepipe-connections may readily be dismantled, and any of the tubes may beremoved 5 independently while the end-plates and gaskets are supportedon the clamping rods.
